Yes/No boxes always have a default value. Often I want a second box to appear if the value is yes, or a third box to appear if the value is no. Because there is a default value for yes/no, my second or third box is always showing.
I don't want this. I only want the second or third box to appear once the user has checked yes or no in the first box.
To get around this I can use a “choice” box with drop downs and have one of the values as null or blank. However, this means that my form contains a mixture of radio buttons and drop downs which looks ugly.
I could use radio buttons for a choice box but then there would be an odd looking null/blank radio button set as default.
Can default be turned off for yes/no boxes?
